Eric Yang commented on YARN-9229:
---------------------------------
Using local attached storage for Docker Registry:
| | Remote | Local |
| Pull | 20.053s | 32.758s |
| Push | 27.601s | 30.194s |
By using NFS gateway, downloading docker image does not introduce overhead in
comparison to using direct attached storage. For docker push, the number is 3
times slower using NFS gateway. NFS Gateway based Docker registry will work
well for cluster that publish docker image occasionally. Hadoop RegistryDNS
seem to be able to parallelize requests to multiple Docker registries without
choking on multiple concurrent downloads.
